Penelitian ini bertujuan untuk memperoleh formula sari biji buah nangka dan sari buah stroberi pada pengolahan susu Nangstro. Penelitian ini terdiri dari dua tahapan penelitian terpisah yang masing-masing dilakukan dengan dengan menggunakan Rancangan Acak Lengkap. Penelitian tahap pertama adalah menentukan formula biji nangka (SBN) dan sari buah stroberi (SBS) dengan perlakuan SBN 80%, SBS 20%; SBN 70%, SBS 30%; SBN 60%, SBS 40%; dan SBN 50%, SBS 50%. Penelitian tahap kedua menentukan umur simpan susu Nangstro dengan perlakuan 0, 3, 6 dan 9 hari. Hasil penelitian menunjukkan bahwa susu Nangstro dengan formula SBN 80% dan SBS 20% dapat diterima oleh panelis. Semakin tinggi kadar SBS dalam formula susu Nangstro akan menurunkan kadar protein, kadar kalsium, total padatan terlarut, dan penerimaan sensorisnya. Kadar SBS yang tinggi akan meningkatkan total asam susu Nangstro. Selama penyimpanan, susu Nangstro mengalami penurunan kadar protein, kalsium dan total padatan terlarut, dilain pihak total asamnya semakin meningkat.
